My dishwasher stopped working and the "Normal" light was flashing. I was told to replace the control assemble board. I ordered it and replaced it and the dishwasher worked for one load. Then the same light started to flash again.
Then the next day it was working again for no reason. The third day I have no lights at all and nothing works. I dont know what to do now?

Here are your parts Replacement parts for WHIRLPOOL GU2400XTPB1 Dishwasher | AppliancePartsPros.comHere is the tech sheet http://www.servicematters.com/docs/wiring/Tech%20Sheet%20-%208535451.pdfIf unit seems totally dead, then I would check to ensure that it is getting power. If OK Next I would check the thermal fuse (Item 6 in Section 2 Parts) On your original problem a flashing key is often a shorted key, see the tech sheet. If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long. If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool. Most places will not let you return electrical parts so if you order it, you own it. A couple things to watch when measuring ohms and continuity 1. Always remove power from the machine otherwise you could blow your meter. 2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path. 3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range. There is a good STICKY at the start of this forum about it's use. |

I have replace the control board and it worked for a couple of washes. Then I replaced the thermal fuse and it worked again for a couple of washes. Then I killed the power and moved the float up and down and it worked for a couple of cycles. Now the original flashing normal light is going and I am unable to wash dishes again.
What else?

The way it was resetting is very weird so I would suspect a bad/dirty connection. Check the wires from the control board that go under the unit.
Try the cleaning procedure below.
Check the Console Assembly (keypad) with a meter, see the tech sheet. |

OOPS!!
Forgot to add it.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try. |

Reconnect everything and give it a try. The ribbon cable goes into the panel through a narrow slot in the plastic. I did not see any obvious way to get into the plastic to inspect the connections. Can you describe a procedure?
